Standard Paper Dimensions
All Dimensions of A series paper are units of the metric system and are most commonly used across the world in countries like India, Singapore, Germany, the UK and many more.
In the late 1700s, France was the first country to adopt the metric system and other countries followed in the 1900s. By the 20th century, most countries adopted metric as a standard.
However the United States and Canada have refused to use metric as a form of measurement for paper sizes. Most of the world uses the international standard of ISO 216 for paper sizes.
Different Units of Measurement
The most commonly known units are millimetres, centimetres, metres and kilometres in metric. However, there are many other types of measurement used to measure length today. Some of these include:
- Inches - 1 Inch = 0.0254m
- Foot - 1 Foot = 0.3048m
- Yards - 1 Yard = 0.9144m
- Miles - 1 Mile = 1609.344m
- Fathom - 1 Fathom = 1.8m
- Shackle - 1 Shackle = 27.4m

What is an Inch of Measurement
The Imperial measurement system is based on dated methods of measurement. For example, the length of 3 Barleycorns is equal to 1 inch. Seeing as Barleycorns can be different in dimensions, it was an unreliable method to measure the size of anything.
The standard of inches is now much more accurate, but is difficult to use compared to the centimetre or millimetre. This is the main reason so many countries have taken on the metric system.
